Techniques for the conveyance of solid combustible material

Abstract

A technique for the conveyance of solid combustible material, having at least one conveying means, wherein the conveying means is supported at least partially by bearing means and/or drive means, in particular on a stand, and the apparatus having at least one collecting space located below the conveying means and having a height, at least one deflecting means for the deflection of solid combustible material towards the collecting space being located below at least one bearing means and/or below at least one drive means. Such an apparatus is suitable most especially for the conveyance of solid materials presenting a fire and/or explosion hazard.

The invention claimed is: 
     
       1. Apparatus for the conveyance of solid combustible material, having at least one conveying means, wherein the conveying means is supported at least partially by a support which is at least one of a bearing means and a drive means, on a stand, and the apparatus having at least one collecting space located below the conveying means and having a height,
 at least one deflecting means, which is constructed and arranged to deflect solid combustible material towards the collecting space, being located directly below the at least one of the bearing means and the drive means. 
 
     
     
       2. Apparatus according to  claim 1 , wherein at least one deflecting means from the following group is located below the conveying means, in particular below the at least one bearing means and/or below the at least one drive means,
 at least one baffle plate, 
 at least one scraping tool, 
 at least one blowing device, and 
 vibrating conveyer. 
 
     
     
       3. Apparatus according to  claim 1 , wherein the at least one deflecting means comprises a baffle plate with an incline of at least 30°. 
     
     
       4. Apparatus according to  claim 3 , wherein the baffle plate comprises reduced friction and/or a sliding coating. 
     
     
       5. Apparatus according to  claim 1 , wherein the height of the collecting space amounts to at least 20 cm. 
     
     
       6. Apparatus according to  claim 1 , wherein the conveying means has mechanical material removers for removal of material from the collecting space. 
     
     
       7. Apparatus according to  claim 6 , wherein the mechanical material removers is located on the conveying means. 
     
     
       8. Apparatus according to  claim 6 , wherein the conveying means has at least one mechanical material remover from the following group:
 scraper, brush, rake. 
 
     
     
       9. Apparatus according to  claim 6 , having a feed region and a dispensing region. 
     
     
       10. Apparatus according to  claim 6 , wherein the conveying means or the mechanical material removers are formed of at least partially of metal. 
     
     
       11. Apparatus according to  claim 1 , wherein the material is conveyable by the conveying means from a material store to a combustion chamber of a combustion boiler. 
     
     
       12. Apparatus according to  claim 1 , having at least one detecting means for:
 a) the filling level of the collecting space, and/or 
 b) the temperature of the material, and/or 
 c) the gas composition in the region of the conveying means. 
 
     
     
       13. Apparatus according to  claim 1 , having at least one extinguishing device. 
     
     
       14. Apparatus according to  claim 13 , having at least one extinguishing control, the extinguishing control being adjusted for activating the at least one extinguishing device. 
     
     
       15. Apparatus according to  claim 1 , wherein the conveying means is located at least partially in a housing. 
     
     
       16. Apparatus according to  claim 6 , wherein a distance between the mechanical material removers and a bottom of the collecting space amounts to 5 mm to 50 mm. 
     
     
       17. Apparatus according to  claim 16 , having an extraction container for the reception of material removed from the collecting space. 
     
     
       18. Apparatus according to  claim 1  wherein the deflecting means includes a set of baffle plates disposed in a lateral manner with respect to the collecting space. 
     
     
       19. A method of conveying solid combustible material, comprising:
 providing an apparatus having at least one conveying means, wherein the conveying means is supported at least partially by a support which is at least one of a bearing means and a drive means, on a stand, and the apparatus having at least one collecting space located below the conveying means and having a height, at least one deflecting means, which is constructed and arranged to deflect solid combustible material towards the collecting space, being located directly below the at least one of the bearing means and the drive means; and 
 transporting, as the solid combustible material, coal and/or pyrite using the apparatus. 
 
     
     
       20. Apparatus for the conveyance of solid combustible material, having at least one conveying means, wherein the conveying means is supported at least partially by bearing means and/or drive means, in particular on a stand, and the apparatus having at least one collecting space located below the conveying means and having a height, at least one deflecting means for the deflection of solid combustible material towards the collecting space being located below at least one bearing means and/or below at least one drive means;
 wherein the apparatus further has at least one extinguishing device, and at least one extinguishing control, the extinguishing control being adjusted for activating the at least one extinguishing device.
